TV star Spencer Matthews and iconic pop band B*Witched are set to appear on the Late Late Show.
A spokesman for RTE confirmed Vogue William's husband will chat to host Ryan Tubridy on the Friday night chat show.
He'll be telling Ryan Tubridy about Finding Michael, the Disney+ documentary about his search for his long-lost brother.
In 1999, Michael Matthews became the youngest Briton to climb Mount Everest. But three hours after he summited, he disappeared and was never found.
Aged just 10 when Michael went missing, his brother, entrepreneur and broadcaster Spencer Matthews, always struggled to accept his death.
In Finding Michael, Spencer retraces his brother's last steps on Mount Everest.
Meanwhile, at the end of last Friday night's show, Ryan Tubridy said he would be welcoming B*Witched as musical guests to the Late Late studio this coming Friday.
The quartet of Edele and Keavy Lynch, Lindsay Armaou and Sinéad O'Carroll are gearing up for the release of new music.
The Late Late Show airs on Fridays on RTÉ One and RTÉ Player at 9.35pm.
